Your Managed WordPress hosting account has a 1GB storage limit on the MySQL database. When a database exceeds that limit, your included backups will not connect with your database, your site could be slower and some of your site’s database functions may not work correctly. Prevent your database from exceeding this limit by removing any overhead data, abnormal comment spam, deleted posts and post revisions.

Check your database size in phpMyAdmin.

Remove overhead data by optimizing the database.

Remove unwanted comments.

Prevent future comment spam by modifying your site’s comment settings.
